nice to have: ICMP handling by router #46
Description
it would be nice if the router implemented some of the traditional ICMP messages for gateways and routers:
- ICMP destination unreachable
- ping requests to its own interfaces
- timestamp requests
- TTL expired (would require OpenFlow support for sure)
and others as discussed in http://tools.ietf.org/html/rfc1812, http://tools.ietf.org/html/rfc1122
Note: this issue is NOT about support for ICMP traffic in the NAT. it is about the router itself issuing ICMP messages.
